Answer:

Option c (2.27) is the right option.

Step-by-step explanation:

As per the question, the values are:

<u>Credit hours                                       Grade                                 fiXi</u>

       (fi)                                                   (Xi)                              

<u>         4                                                  B = 3                                   12</u>

<u>         3                                                  C = 2                                   6</u>

<u>         1                                                   A = 4                                   4</u>

<u>         3                                                  D = 1                                    3       </u>

Now,

\Sigma fi= 25

\Sigma fiXi = 25

hence,

The average will be:

= \frac{\Sigma fiXi}{\Sigma fi}

On putting the values, we get

= \frac{25}{11}

= 2.27

miv72 [106K]

Answer:

The probability that a house has a backyard given that has a garage is 76.60%.

Step-by-step explanation:

Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:

47 = 100

36 = X

(36 x 100) / 47 = X

3,600 / 47 = X

76.5957 = X

Therefore, the probability that a house has a backyard given that has a garage is 76.60%.

6. Find the total bill:
daser333 [38]

First multiply all the items up with their correct prices.

5 Golf Clubs = 18.65 each

5 x 18.65 = 93.25

60 Golf Balls = 16.50 per dozen

60 = 5 dozen

5 x 16.50 = 82.5

1 pair of golf shoes = 75.80

1 x 75.80 = 75.80

Now, add them all up.

93.25 + 82.5 + 75.80 = 251.55

Lastly, multiply by 1.15 to add the 15% sales tax.

251.55 x 1.15 = 289.28

Thus, the total cost of all the equipment with tax is $289.28
